Radial Engineering JS-3 Three-Way Microphone Signal Splitter – Transformer-Isolated Mic Splitter for Triple Output Routing in Live Sound and Studio Applications

The Radial Engineering JS-3 Three-Way Microphone Signal Splitter is a professional passive transformer-isolated mic splitting system designed for live sound, broadcast, and studio environments where a single microphone signal must be distributed to multiple destinations with maximum clarity and isolation.

The JS-3 takes one microphone input and splits it into three outputs: one direct (dry) output and two fully transformer-isolated outputs. This configuration allows engineers to send the same mic signal simultaneously to systems such as front-of-house mixing consoles, monitor desks, recording devices, and broadcast feeds, all while maintaining clean separation between each signal path.

At the core of the unit are premium Jensen transformers, which provide high-quality galvanic isolation on the split outputs. This eliminates ground loops, hum, and electrical noise that often occur when multiple audio systems are connected to a single microphone source. The result is stable, noise-free signal distribution across all connected devices.

Because the JS-3 is fully passive, it requires no external power and maintains a completely transparent signal path. It preserves the natural tone and dynamics of the microphone, ensuring that each output remains faithful to the original source without added coloration or distortion.

Key Features:

• 1-in / 3-out microphone signal splitter for professional audio routing
• One direct output plus two transformer-isolated outputs
• High-quality Jensen transformers for superior isolation and noise rejection
• Eliminates ground loops and prevents hum in multi-system setups
• Fully passive design with no power required
• Transparent signal path with minimal coloration
• Ideal for live sound, broadcast, theater, and studio applications
